If your application demands a different material, please contact Alicat.
1. In addition to all non-corrosive gases, PS Gauges are configured to operate with the following aggressive
gases: Ammonia, Chlorine, Hydrogen Sulfide, Nitric Oxide, Nitrogen Dioxide, Nitrogen Triflouride, Propylene,
Sulfur Dioxide. The following gases are available upon request: Refrigerant gases to 100% (Refrigerant gases
my require custom seals, consult Alicat.) If your application requires another gas or gas mixture, please contact
Alicat. For use with water or other liquids please contact Alicat.
